Boneham AM00000046 Drill Bushing Hm 15.5 in Id

Product Description

The BONEHAM AM00000046 is a press fit headless drill bushing with an HM industry code designation, designed to guide drill bits and other cutting tools with precision during machining and fabrication operations. Made from hardened steel with a surface hardness of 60 to 65 HRC, it resists wear under repeated tooling passes. The bushing features a 15.5-inch inside diameter and is installed by pressing directly into a jig plate or fixture body without a head or locking collar. It is a non-renewable design, meaning it is intended for permanent installation in the tooling fixture. Machinists, toolmakers, and maintenance personnel in manufacturing and metalworking environments install this bushing as part of drill jig assemblies.

This drill bushing is suited for use in drill jigs and tooling fixtures in industrial machining, production fabrication, and maintenance repair environments. It is appropriate for applications requiring consistent hole location accuracy across high-volume drilling cycles. The HM code designates its dimensional series per ANSI standards, making it a recognized fit within standard jig bushing interchangeability systems. It is used in both light production and heavy-duty machining setups where a permanent, press-in guide bushing is the specified solution.

Key Features

• Press fit installation — no head or locking collar required for secure seating in jig plate
• Hardened steel construction with 60 to 65 HRC surface hardness for extended wear resistance
• HM industry code designation per ANSI standards for dimensional interchangeability
• Non-renewable design intended for permanent fixture installation
• Inside diameter tolerance of +0.006 to +0.017 mm for precise tool guidance
• Inside diameter of 15.5 inches with 26.00 mm body outside diameter

Compatibility

Designed as a standard HM-series press fit headless drill bushing per ANSI specifications, suitable for use in drill jigs and tooling fixtures that accept HM-code bushings of this dimensional series.

Installation Notes

Installation is performed by toolmakers or machinist personnel using a press or arbor press to seat the bushing flush within the jig plate bore. The receiving bore in the fixture plate must be machined to the appropriate interference fit tolerance before pressing the bushing in place. Do not drive the bushing in with impact tools, as this can damage the bore or distort the bushing geometry. Once pressed in, this bushing is not designed for removal and reinstallation.
